"Throughout this project we had to factor in that the product should be low in energy consumption, small enough and think this product for fills that brief. We are looking forward to working with EasyJet on this project."

The EasyJet Sneakair prototype is planned to be rolled out for its passengers to purchase on-board in the future.
